Be it known that I, EDWIN H. WoLrr,

'a citizen of the United States, residing at to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of, reference marked thereon, which form a part of this specification; V

This invention relates to stove pipe fasteners, and particularly to means for securing the end of a stove pipe within the flue or chimney- The invention contemplates the provision of means whereby the pipe may be conveniently introduced into the flue opening and fastened against accidental I displacement.

In the drawings:

Figure l'is a perspective view of theend of a pipe to which my invention isapplied, the securing device being shown in the nonfunctional position.

Fig. 2 is a similar view showing the se-v curing-device in functional position.

Fig. 3 is a sectional view through a flue andpipe showing the fastening device in its securing position.

In carrying out the 1nvent1on I provide a stove plpesectlon 1, near one end of wh ch the cuts are made,- as at 2 and 3, so that the portions of the section opposite the cuts constitute webs or strips 4 and 5, which may be in-bent to provide bearings for a bolt 6. The portions 7 and 8 of the webs have alining openings for the bolt 6, as indicated in Fig. 1. There is a rigid collar 9 on the bolt 6 intermediate its ends so as to constitute a stop, the stop being so posi tioned on thebolt 6 as to provide a short portion 10 and a long portion 11. Therefore, when the collar 9 restsupon the bear-.

ing portion 8, the'end of the bolt 11 projects beyond the edge or perimeter of the pipe, but when the collar rests upon the bearing 7 the entire bolt will be within the V V Specification of Letters Patent. Pa'tented Sept, 20, 1921. v V Application-filed August 11, 1920. Serial No. 402,770.

circumference of the pipe. Therefore when it is desired to apply the endof the pipe to the flue or chimney 12, the pipe willbe turned so that the bolt 6 will be in the positlon shown in Fig. 1, and after the pipe has entered the flue opening it will be turned so that the bolt may assume the position shown in Fig. 2,'whereupon the end 11 of the bolt 6 will overlap the lower edge 13 of the flue opening 14 and thereby prevent the accidental removal of the pipe, since the bolt end 11 will constitute a lock for the cient and durable fastening means for stove pipes is provided.

What .I clalm and desire to secure by Letters-Patentis:

j 1'. A stove pipe having inbent webs at @116 end, and a bolt mounted and slidable in the webs and movable in one direction to extend beyond the perimeter of the pipe and movable in the opposite direction to a position within the perimeter of the pipe.

2. A' stove pipe having bearings at one end, and a retaining bolt slidable in the bearings, normally within the perimeter of the pipe but projectable beyond the same to abut against'the inner face of a flue wall hold the pipe in the flue opening.

3. A stove pipe, the wall of which is oppositely out near one end of the pipe to provide webs,'the webs being bent inwardly toward one another to provide bearings, a bolt slidably mounted in the bearings, and a stop collar on the bolt to provide a long portion and 'a short portion whereby the olt may normally be confined within the perimeter of the pipe when the collar rests against one hearing but projects beyond the perimeterof the pipe when the collar rests against the other bearing.

4. A stove pipe out near one end to pro-- vide diametrically opposite, inbent, web portions having alining openings, a bolt slidably mounted in the openings, and a collar onone side of the transverse center. of the bolt to provide a long portion and a short portion, the length of the bolt being substantially equal to the diameter of the pipe'whereby when the collar rests'against one Web, the bolt will be confined within the perimeter of the pipeand when the collar rests against the other Web, one end of the bolt will project beyond the perimeter 10 of the pipe; p

In testimony whereof I alfix my signature.

EDWIN H. WOLFE.
